Electrosynthesis of ortho‐Amino Aryl Ketones by Aerobic Electrooxidative Cleavage of the C(2)=C(3)/C(2)−N Bonds of N‐Boc Indoles

The previous strategies for oxidative cleavage of 2,3‐double bond of substituted indoles generally suffered from usage of heavy metals, stoichiometric chemical oxidants or hash conditions. Herein, we reported an electrochemistry‐driven aerobic cleavage of C(2)=C(3)/C(2)−N bonds of indoles. Through an undivided cell, various indoles and its derivatives can be converted into the corresponding ortho‐amino aryl ketones. This method features metal‐free, air‐as‐oxidant and easy scalability.
